Previously on ER.

As television's most Emmy-nominated series (fact) comes to a close, this hour-long retrospective takes a look back at the past 15 seasons at Chicago's County General ER. Clips from the most memorable episodes (heavily involving Mr. Clooney, we hope) will be featured along with interviews with many of the past and present stars of ER. At 9.25pm, an extended edition to mark the final episode of the long-running drama will be shown. Yip, no more TV promos announcing the final series of ER… Old friends return to show their support at the opening of a new medical facility for the underprivileged, and Sam receives a special gift for her birthday. Gates helps a teenager suffering from alcohol poisoning after playing a drinking game, while Carter tries to save a mother in labour with twins. Linda Cardellini stars. Last in the series. Ever.
